What is the effect of silicon fertilizer on rice? What is the harm of excessive potassium fertilizer on rice?

At present, there are many people growing rice in our country. Our country has a large population, and rice is also the main food eaten by our people. If you want rice to grow well, then fertilization is critical, but there are also skills in waste water. If some fertilizers are applied too much, it may cause a lot of harm, so how to raise the common potash fertilizer if you apply too much potash fertilizer?

What is the effect of silicon fertilizer on rice?

1. Silicon fertilizer can increase rice yield and improve rice quality. most of the paddy soils in the north are white serous soil and meadow soil. the old paddy fields absorb a large amount of silicon from the soil every year, resulting in serious lack of silicon in paddy fields, poor growth of rice, slender and weak stems, leaves from erect type to weeping willow leaves, many empty chaff grains, decrease in 1000-grain weight, lodging, rice blast, rice stem borer and other diseases and pests easily occur.

2. Silicon fertilizer is beneficial to improve the photosynthesis of rice. After absorbing silicon, rice forms silicified cells, enhances the strength of cell wall, and makes plant mechanical tissue developed, plant type tall and straight, stems and leaves erect. The angle between rice stems and leaves decreased by 25.4 degrees, which was beneficial to ventilation, light transmission and close planting, photosynthesis of rice leaves, and accumulation of organic matter, thus increasing rice yield.

3. Silicon fertilizer can enhance the resistance of rice to diseases and insect pests. The formation of silicified cells thickens the surface cell wall and increases the quality of the cuticle of rice, so as to enhance the resistance to diseases and insect pests, especially rice blast, rice sheath blight, rice leaf spot and so on.

What is the harm of excessive potash fertilizer to rice?

1. Excessive potassium application will not only waste valuable resources, but also reduce the absorption of calcium and other cations by crops, resulting in leaf vegetable rot heart disease, apple acne disease and so on.

2. Excessive application of potassium fertilizer will cause soil environmental pollution and water pollution.

3. Excessive application of potassium fertilizer will weaken the production capacity of crops.

How much silicon fertilizer is used in one mu of land?

The application amount of silicon fertilizer should be determined according to the content of available silicon in soil and the content of water-soluble silicon in silicon fertilizer. The soil with severe silicon deficiency can be applied more appropriately, while the soil with mild silicon deficiency should be applied less. Water-soluble silicon fertilizer with 50-60% available silicon content can be applied 6-10 kg per mu; steel slag silicon fertilizer with 30-40% available silicon content can be applied 30-50 kg per mu; and 50-100 kg per mu can be applied if the available silicon content is less than 30%.

Fertilization methods for High yield of Rice

1. Base fertilizer is the basis of rice growth, so the suitable amount of base fertilizer must be sufficient. Base fertilizer accounts for a large proportion in the process of rice growth. Usually, we usually sprinkle some farm fertilizer and ammonia fertilizer. In fact, the best way to use base fertilizer is a mixture of rotten fertilizer and organic fertilizer, while applying a small amount of chemical fertilizer, mainly phosphate fertilizer and potash fertilizer, of course, you can also add a little nitrogen fertilizer. However, it is recommended that in the early stage of rice growth, try not to use too much nitrogen fertilizer and other chemical fertilizer, apply base fertilizer as deep as possible, so as to maintain fertility.

2. Tillering fertilizer usually begins to be fertilized about a week after transplanting rice seedlings, and the amount of fertilization this time should not be too fierce, because rice tillering only needs an appropriate amount of fertility, and if the force is too strong, it will produce a lot of invalid tillers of rice. This will not only not increase the yield of rice, but also reduce the yield. The best fertilizer for rice at tillering stage is available organic fertilizer plus a little urea and livestock manure. Tillering fertilizer is generally carried out in batches in order to prevent excessive force, so it is generally applied less at a time, and if the tillering of rice in the field is relatively slow, it is good to apply it again.

A good application of silicon fertilizer can make the rice grow well and prevent some insect pests. If potash fertilizer is applied too much, we may make rice sick and pollute the environment. Usually when applying silicon fertilizer, the amount of silicon per mu should be determined according to the content of silicon in it.
